BAILING APPARATUS.

SPECIFICATION forming part of Letters Patent No. 638,948, dated December12, 1899.

Application filed October 25, 1898; Serial No. 694,551. (No model.)

My invention relates to deep-well hailing apparatus, and has for itsobject to provide a portable apparatus adapted to be operated by horse-power for effectually controlling the elevation andlowering of abailer, the various movable parts of the apparatus being actuated bymeanswithin reach and underthe control of a single operator.

Further objects and advantages of this invention will appear in thefollowing description, and the novel features thereof will beparticularly pointed out in the appended claims.

In the drawings, Figure 1 is a perspective view of an apparatusconstructed in accordance with my invention. Fig. 2 is a verticalsection of the same, showing the tilting shaft elevated. Fig. 3 is aplan view, partly in section, to show the means for adjusting thebearing-rolls with relation to the master-gear and the means whereby thestrut-supports of the tilting shaft are mounted upon the standards ofthe frame. Fig. 4i is a partial vertical section at right angles to theplane of Fig. 2 to show the stop-pawl and coperatin g means forpreventing the backward movement of the bailer during the elevationthereof. Fig. 5 is a detail sectional view of the connect-ion betweenthe rear ends of the bearing-block braces and the standard of thesupporting-frame. Fig. 6 is a similar view of the connection between thebearing-block and the front ends of the braces. Fig. 7 is a detailvertical section to show the means of adjustment for thebearing-roller-supporting frame. Fig. 8 is a detail view in perspectiveof the adjacent extremities of the operatinglever, draw-rod,brake-lever, &c.

Similar reference characters indicate corresponding parts yin all theiigures of the drawings.

Mounted upon a suitable truck or supporting-frame 1, which may havesupportingwheels to adapt it for movement to and from the point at whichthe apparatus is to be used, is a horizontal master-gear 2, upheld formovement by supporting-rollers 31, mounted upon said truck orsupporting-frame, and mounted upon a suitable superstructure rising fromsaid truck or supporting-frame is a tilting drum-shaft 4, having apinion 5, of

which the teeth normally mesh with those of the master-gear, said shaftbeing mounted for swinging movement toward and from the plane of themaster-gear. Said superstructure includes standards 6 and 7, rising fromthe truck or supporting-frame, and an up-` provided at an intermediatepoint with a rigid depending bifurcated arm 14, pivotally mounted uponthe frame-bar 12, and to a bearing-block 15, in which is mounted the,other trunnion or gudgeon of the drum-shaft,

is connected the extremity of said operatinglever by means of links 16,which are rigid with the bearing-block, whereby in moving the free orhandle end of the operating-lever the bearing-block 15 travels in a pathapproximately concentric with the opposite extremity of the drum-shaftto avoid twisting or straining that trunnion or gudgeon which is mountedin said bearing-block. Also the said links 15' form lateral guides whichoperate upon opposite sides of the front end of the frame-bar 12 toinsure the reciprocation in a truly vert-ical plane of the bearing-block15.

Mounted for reci procatory movement upon the frame-har 12 is a slide 17,itted in suitable 0"uides 1S and provided with a stop or enlargement 19,which is adapted when the slide is extended for arrangement in the pathof a shoulder 20 on the bearing-block 15, whereby said stop forms a lockto securethe bearingblock in its depressed position againstvverticalmovement, and thus to effectually maintain the teeth of the pinion 5 inoperative engagement with the teeth of the master-gear. Connected at anintermediate point with the IOO slide is a lever 2l, mounted upon theframe and having in connection therewith an operating-rod 22, whichterminates at a point near the vertical plane of the rear end of theoperating-lever 13, whereby said operating-rod may be grasped withfacility by an operator positioned to manipulate said operating-lever.

The drum-shaft 4 carries an armed drum 23, to which is attached one endof a bailer-cable 24, said cable extending at an intermediate point overan elevated direction pulley or sheave 25, supported by a derrick 26 orother equivalent frame, and also arranged upon the drum-shaft,preferably contiguous. to the drum, as illustrated in the drawings, is abrake-wheel 27, encircled by a contractible brake-strap 28, with whichis connected one arm of a brakedever 29, also located within reach of anoperator positioned to manipulate the lever 13. Inv the constructionillustrated the brake-lever is provided with an intermediate spindleportion, which is mounted in a bearing located upon the upright 8.

To maintain the bearing-block 15 in its proper position with relation tothe other elements of the mechanism, I employ pivotal' to swing invertical planes when the hearingblock is elevated and depressed. Saidtapered keys may be adjusted to vary the forward4 pressure of the braces30 and are adapted to be secured at the desired adjustment by means ofpins 34, engaged with openings in the keys and bearing against the innersurfaces of the braces. To maintain lthe bearing-block and strut-bracesin their proper relative positions, I em ploy tension-braces 35,extending from said bearing-block rearwardly to and through thestandards 6 and fitted at their rear edges with adjusting-nuts 36. Alsocarried by the drum-shaft is a stop-gear 37, of which the teeth areadapted for engagement with the extremity of a pivotal stoppawl 38,mounted upon one of the standards 6 and normally held in an elevated orinoperative position by means of a liexible connection 39, consisting ofa chain, cable, or equivalent thereof extending over a suitable guide 40on the crossbar 11 and adapted for engagement at its rear end with aholding device or catch 4l. By disengaging the connection from the catchthe stop-pawl may be lowered to arrange its free end in operativerelation with the stop-gear, whereby during the elevation of abailing-bucket the disarrangement of the operating-gears will not causethe dropping of the bailing-bucket for the reason that said pawl willlock the drumshaft against backward rotation.

Arranged in operative relation with the inner periphery of the rim ofthe master-gear for holding the latter against vibration upon its seat(formed by the above-described supporting-rolls) are bearing-rolls 42and 43, which are mounted in pairs upon forwardly and rearwardlyadjustable frames, each consisting of upper and lower transverse bars 44and 45. These adjustable frames, between the extremities oi the bars ofwhich are mounted said bearing-rolls, are connected with the standards 6and 7, respectively, by means of adjusting-bolts 46, and insertedbetween said frames and the contiguous surfaces of the standards arewedges 47. By loosening the said bolts and suitably adjusting the wedgesfthe frames may be moved either toward or from each other, which adaptsthe rolls at the extremities of the frames to be moved in pairs inparallel chords of a circle formed by the master-gear. Thus it will beseen that these rolls are adjusted obliquely to a radius and as may benecessary in connection with the rim of the master-gear to insure acloser bearing or reducing the pressure, and thus confine the mastengearoperatively in the desired position upon the supporting-rolls. Alsoconnecting the standards 7 and terminally overlapping the rim of themaster-gear is a retaining-bar 48 to prevent the vertical displacementof said gear.

The master-gear is adapted to be operated by horse-power, and a simplemeans whereby such power may be'applied to the mastergear consists of asweep 4t), of which one or more may be employed,v pivotally mounted atits inner end on the outer face of the master-gear for vertical swingingmovement, provided at its outer end wit-l1 a suitable elevis 50 for thewhifiietree to which the power is applied and held in the desiredposition against forward displacementunder strain by means of a tensionrod or brace 5l, while the whiftletree supports the outer endvertically, yet permits it to yield as may be necessary to conform withthe height of the animals hitched thereto.

In operation the tilting shaft, by which the pinion 5 is carried, may beelevated to disengage said pinion from the master-gear to allow backwardrotation of the drum, and such backward rotation may be controlled as tospeed by means of the brake mechanism hereinbefore described. Also whenthe tilting shaft is depressed and the receiving-gear or pinion 5 is inoperative engagement with the driving or master gear 2 the slide 17 maybe moved forward to lock the forward bearing of said shaft in itsdepressed position, and during the elevation of a hailing-bucket thestop-pawl 38 may be released to allow its free end to drop intooperative relation with the stop-gear 37, whereby accidental backwardrotation of the drum-shaft is prevented.

It will be seen from the foregoing description that I have provided asimple, comparatively inexpeusive,and efficient apparatus for bailingpurposes which `may be moved by IOO TIO

horse-power to the point of use over a well to be bailed and of whichthe operating parts may be controlled by a single attendant lo.

cated within reach of the operating-lever 13, and also of theoperating-rod 22 and brakelever 29, and it will be understood,furthermore, that various changes in the form, proportion, and the minordetails of construction may be resorted to without departing from thespirit or sacrificing any of the advantages of the invention.

In the construction illustrated the derrick consists of a plurality oftimbers separate from the supporting-frame of the operating mechanism,suitably connected at their upper ends and adapted to rest at theirlower ends upon or be embedded in the soil, said lower ends being spacedfrom the supportin frame or truck of the mechanism at such a distance asto allow the animals by which power is communicated to the master-gearto move under the derrick-beams or within the circle described by thelower ends of said beams. This construction provides for lightness, andhence increased portability, of the operating mechanism, While givingthe operator the necessary control of the various movable elements ofthe machine. Furthermore, it will be observed that by the use of anannular master-gear having its center wholly open I am enabledtomakeitof asufliciently large diameter to obtain a firm and steadybearing upon the supporting-framework-and at the same time allow thebailer-cable to operate therethrough, and thus economize the spacerequired in which to operate the machine. The drum also is located atthe longitudinal center of the framework, and hence the upward strainapplied thereto in the operation of elevating the hailing-bucket isapproximately in alinement with the center of the structure.

In operation a hailing-bucket of the ordinary construction is lowered bymeans of the cable and operating devices into a well, is filled with thesand or other material contained in the well, and is withdrawn therefromin order to put the well into condition for further drilling or forpumping. The operation of bailing a well is so well known in the art asto require no more specific statement.
